The India Meteorological Department (IMD) has forecast the development of a depression over the Bay of Bengal by November 15, 2026, raising the possibility of heavy rainfall over the Andaman Islands. A low-pressure area formed over the Southeast Bay of Bengal at 5:30 am IST on November 13 under the influence of an upper-air cyclonic circulation over the central Andaman Sea. According to the weather department, the system extends up to the middle tropospheric levels and is expected to move northwestwards. It is likely to intensify into a well-marked low-pressure area around November 14 before developing further into a depression over the same region by November 15. The developing system is being closely monitored as it gathers strength over the Bay of Bengal.
Meanwhile, weather conditions across several parts of the country are also being influenced by other atmospheric systems. An active Western Disturbance, persisting as a cyclonic circulation over the Kashmir division, is contributing to wet weather over Northwest India. Additional upper-air cyclonic circulations are present over Sikkim and its neighbourhood, the southeast Arabian Sea adjoining south Lakshadweep, and the Gulf of Mannar. These weather systems are influencing atmospheric conditions across their respective regions. With the low-pressure system over the Southeast Bay of Bengal expected to strengthen in the coming days, the IMD has indicated the possibility of heavy rainfall over the Andaman Islands as the system progresses towards depression intensity.
